Description
DK 152538 BDK 152538 B
Den foreliggende opfindelse angår et tværstykke til en dækkæde til anbringelse på et dæk til sikring mod skridning og nærmere betegnet et kabeltværstykke, der forløber igennem gribemuffer.The present invention relates to a crosspiece for a tire chain for mounting on a tire for anti-slip and, more specifically, a cable crosspiece extending through gripping sleeves.
Dækkæder af enten ledtype eller af kabeltype er velkendte.Tire chains of either joint type or cable type are well known.
05 Begge typer er udsat for slitage, især når der køres pi tør vej eller med høje hastigheder, og begge typer har tendens til at forøge dækslitagen. Endvidere kan mange dækkæder ikke anvendes på køretøjer, der har begrænset frigang imellem dækket og karrosseriet.05 Both types are subject to wear, especially when driving on dry roads or at high speeds, and both types tend to increase tire wear. Furthermore, many tire chains cannot be used on vehicles that have limited clearance between the tire and the bodywork.
Fra US patentskrift nr. 4.155.389 kendes en dækkæde med side-10 stykker indrettet til anbringelse i hovedsagen i omkredsretningen på modstående sider af dæk og med en flerhed af tværstykker forbundet til og forløbende mellem sidestykkerne hen over dækkets slidbane, idet begge sidestykkerne og tværstykkerne består af fleksibelt kabel, og idet kablet i hvert sidestykke bærer en flerhed af 15 gribemuffer derpå, som under brugen forløber i det væsentlige uden mellemrum fra den ene side af dækket til den modsatte side hen over dækkets slidbane. Når et dæk roterer med en sådan dækkæde, løfter centrifugal kræfterne den midterste del af tværstykkerne længst muligt bort fra dækket, hvorved midterstykkerne accelereres til højere 20 hastigheder og tvinges ned i vejen med betydelig slagvirkning. Tværstykkerne udsættes derfor for betydelig slidtage.US Patent No. 4,155,389 discloses a tire chain with side pieces arranged for positioning substantially in the circumferential direction on opposite sides of the tire and with a plurality of cross pieces connected to and extending between the side pieces over the tire tread, both side pieces and the cross pieces is made up of flexible cable, and the cable in each side carries a plurality of 15 gripping sleeves thereon which during use extend substantially without gap from one side of the tire to the opposite side across the tire tread. When a tire rotates with such a tire chain, centrifugal forces lift the middle portion of the cross sections as far away as possible from the tire, accelerating the center pieces to higher speeds and forcing them into the road with significant impact. The cross pieces are therefore subject to considerable wear.
Der kendes dækkæder af kædetype omfattende to sidekæder indrettet til anbringelse i hovedsagen i omkredsretningen på modstående sider af dæk og med tværkæder, der forløber mellem sidestykkerne 25 og hen over dækkets slidbane, hvor tværkæderne omfatter gribe-klamper eller gribejern anbragt ved dækkets sider. Klamperne er anbragt således, at de ved kørsel på et fladt underlag ikke rører underlaget, men først i det tilfælde, at dækket synker ned i et blødt underlag såsom sne eller mudder, bliver aktive. P.g.a. dis-30 se indretningers karakter er klamperne nødt til at være forholdsvis brede og tunge, og det er klart, at de kunne påføre betydeligt og meget koncentreret slid på dækket, hvis de kom til at køre på underlaget over længere tidsrum. Endvidere ville klamperne selv være udsat for bortslidning af deres finner, således at de derpå ville tabe 35 deres skrid-hindrende virkning.There are known chain-type tire chains comprising two side chains arranged for positioning substantially in the circumferential direction on opposite sides of the tire and with cross-chains extending between the side pieces 25 and across the tire tread, the cross-chains comprising gripper clamps or gripper bars disposed at the tire sides. The cleats are arranged so that when driving on a flat surface they do not touch the substrate, but only in the event that the tire sinks into a soft substrate such as snow or mud, becomes active. P.g.a. In the nature of these devices, the cleats have to be relatively wide and heavy, and it is clear that they could inflict considerable and very concentrated wear on the tire if they were to run on the surface over extended periods of time. Furthermore, the cleats themselves would be subject to wear and tear of their fins, so that they would then lose their anti-slip effect.
Opfindelsen har til formål at tilvejebringe et tværstykke til en dækkæde, således at der opnås forbedret trækevne og mindre slita- 2The invention has for its object to provide a crosspiece for a tire chain so as to achieve improved traction and less wear and tear.

ge pi såvel dæk som pi kæde, og således at dækkæden kan anvendes på køretøjer med begrænset frigang imellem dækkene og køretøjets karrosseri .both in tires and in chains, and so that the tire chain can be used on vehicles with limited clearance between the tires and the body of the vehicle.
Dette opnås med et tværstykke til en dækkæde, hvilket tvær-05 stykke er forbundet med to sidestykker, der er indrettet til anbringelse i hovedsagen i omkredsretningen på modstående sider af et dæk, hvilket tværstykke består af et kabel, som forløber mellem sidestykkerne hen over dækkets slidbane og som ved kablets modstående ender er forbundet med sidestykkerne samt har et antal roterbare 10 drivkraftoverførende gribemuffer eller bøsninger, igennem hvilke kablet forløbet, hvilket tværstykke er ejendommeligt ved, at de drivkraft-overførende gribemuffer er anbragt og fastholdt pi kablet på steder herpå, som under brugen befinder sig ved dækkets kanter, mens den del af kablet, som under brugen befinder sig ved dækslid-15 banens midte, er uden sådanne gribemuffer.This is accomplished by a tire cross section, which cross-05 piece is connected to two side pieces arranged for positioning substantially in the circumferential direction on opposite sides of a tire, which consists of a cable extending between the side pieces across the tire tread and which at the opposite ends of the cable are connected to the side pieces and have a plurality of rotatable drive-transmitting gripping sleeves or bushes through which the cable passed, which is peculiar in that the driving-transmitting gripping sleeves are arranged and secured to the cable in places thereon. during use is at the edges of the tire, while the part of the cable which is in use at the center of the tire tread is without such gripping sleeves.
Hermed opnås en dækkæde med ringe vægt, hvilket betyder mindre slitage på dæk og kæde og desuden mindsker kædens fremstillingsomkostninger. Det har endvidere vist sig, at der opnås en forøgelse i trækevnen ved at begrænse mufferne til kun dækkanter-20 ne.This results in a lightweight tire chain, which means less tire and chain wear and also reduces the chain's manufacturing costs. Furthermore, it has been found that an increase in traction is achieved by limiting the sleeves to only the tire edges.
Ifølge en særlig udførelsesform af opfindelsen har kablet i tværstykket en krog i hver ende, hvor hver krog er udformet af et rektangulært metalstykke, hvis ene endedel er ombukket med henblik på forbindelse direkte med et sidestykke, mens en modstående ende-25 del er udformet til en cylinder til optagelse og gribning af en ende af kablet. Dette mindsker yderligere dækkædens vægt og pladsbehov.According to a particular embodiment of the invention, the cable in the crosspiece has a hook at each end, each hook formed of a rectangular metal piece, one end of which is folded for direct connection with a side piece, while an opposite end part is formed for a cylinder for receiving and gripping one end of the cable. This further reduces the weight and space requirements of the tire chain.
I det følgende skal opfindelsen beskrives nærmere under henvisning til tegningen, hvor fig. 1 er et perspektivisk billede af en dækkæde ifølge opfindel-30 sen V|St påsat på et køretøjsdæk, fig. 2 et forstørret tværsnitsbillede taget i hovedsagen i planet 2-2 i fig. 1, og fig. 3 og 4 til hinanden svarende perspektiviske billeder af to udførelsesformer for tværstykket.In the following, the invention will be described in more detail with reference to the drawing, in which fig. 1 is a perspective view of a tire chain according to the invention V | St mounted on a vehicle tire; FIG. 2 is an enlarged cross-sectional view taken substantially in plane 2-2 of FIG. 1, and FIG. 3 and 4 are perspective views corresponding to two embodiments of the crosspiece.

3 står af kabel såsom flerslået stålkabel. Tværstykkernes kabler er ført igennem et antal gribemuffer 16. Sidestykkerne kan også være udformet af andre typer af langstrakt, fleksibelt materiale. I det mindste det ene af sidestykkerne indeholder en samling 18 for at mulig-05 gøre, at dækkæden 10 monteres på et dæk 20 på et køretøjshjul 22. Tværstykkerne er forsynet med kroge 26, der beskrives nærmere senere, til at forbinde tværstykkerne direkte med sidestykkerne.3 stands of cable such as multilayered steel cable. The cables of the cross pieces are passed through a number of gripping sleeves 16. The side pieces can also be formed of other types of elongated, flexible material. At least one of the side pieces includes an assembly 18 to enable tire chain 10 to be mounted on a tire 20 on a vehicle wheel 22. The cross pieces are provided with hooks 26, described later, to connect the cross pieces directly to the side pieces .
Idet der henvises specielt til fig. 2 og 3, består hvert tværstykke af et kabel 28, der bærer flere trækmuffer 16. Trækmufferne ^0 er fortrinsvis af den i USA patentskrift nr. 4.155.389 beskrevne type, som er udformet ved bøjning af et i hovedsagen rektangulært metalstykke til en cylindrisk form og med afstandstunger 30 til adskillelse af til hinanden stødende muffer samt med skarpe bidekanter 32, 34. Som et fremtrædende træk er trækmufferne kun anbragt på 1 s dele af tværstykket, som befinder sig ved dækkets kanter 40, således som det fremgår tydeligt af fig. 2. Den del 42 af tværstykket, som ligger ved dækslidbanens midterområde 44, er fri for trækmuffer.Referring specifically to FIG. 2 and 3, each transverse piece consists of a cable 28 carrying multiple pulling sleeves 16. The tensioning sleeves 0 are preferably of the type described in U.S. Patent No. 4,155,389 which is formed by bending a generally rectangular metal piece to a cylindrical shape and with spacer tongs 30 for separating adjacent sleeves as well as with sharp bite edges 32, 34. As a prominent feature, the pull sleeves are placed only on 1 s parts of the crosspiece which are at the edges 40 of the tire, as can be clearly seen in FIG. . 2. The part 42 of the crosspiece, which lies at the center area 44 of the tire tread, is free of tension sleeves.
For at holde trækmufferne i position på tværstykkets kabel 28 i områder ved dækkanterne og for at hindre mufferne i at bevæge sig 20 til dele af kablet ved dækslidbanens midterområde, kan der være anbragt en skruefjeder 46 på kablet 28 i den midterste del af tværstykket ved slidbanens midterparti som vist i fig. 2 og 3. Lignende skruefjedre 48 kan være anbragt på tværstykkets kabel ved dæksidevæggene 50 for at hindre trækmufferne i at glide for højt op på side-25 væggen.In order to keep the tensioning sleeves in position on the crosspiece cable 28 in areas at the tire edges and to prevent the sleeves from moving 20 to parts of the cable at the center area of the tire tread, a screw spring 46 may be mounted on the cable 28 in the middle part of the crosspiece at the tread. middle portion as shown in FIG. 2 and 3. Similar coil springs 48 may be provided on the cross piece cable at the cover side walls 50 to prevent the tugs from sliding too high up the side 25 wall.
Fig. 4 viser en anden udførelsesform for tværstykket. I stedet for en skruefjeder kan der anvendes to stop 52, som er fastgjort på kablet 28, som afstandsstykker til at holde trækmufferne på dækkanterne. Stoppene 52 kan være stålstykker, der krympet, svejst eller 30 på anden måde fastgjort på kablet 28. Lignende stop 54 kan også være fastgjort på kablet imellem krogene 26 og trækmufferne 16 for at holde trækmufferne i afstand fra krogene og for at fastholde mufferne på de korrekte steder på tværstykkets kabel.FIG. 4 shows another embodiment of the crosspiece. Instead of a coil spring, two stops 52, attached to the cable 28, can be used as spacers to hold the tensioning sleeves on the tire edges. The stops 52 may be steel pieces which are shrunk, welded or otherwise secured to the cable 28. Similar stops 54 may also be attached to the cable between the hooks 26 and the tensioning sleeves 16 to keep the tensioning sleeves away from the hooks and to secure the sleeves to the hooks. correct places on the cross piece cable.

Siderne 58 af metalstykkets anden endedel, der ligger modsat den ombukkede ende 56, kan være bøjet sammen 05 omkring en anden akse, som stir vinkelret pi den første akse, til dannelse af en cylindrisk del til optagelse og fastgribning af enden 60 af kablet 28. Krogene kan være fastgjort til kabelenderne, eksempelvis ved krympning eller svejsning.of the metal piece is bent around a first axis to form a hook portion which may be shrunk or otherwise attached to the side pieces (Fig. 2). The sides 58 of the second end portion of the metal piece, which is opposite to the folded end 56, may be bent together 05 about a second axis perpendicular to the first axis to form a cylindrical portion for receiving and grasping the end 60 of the cable 28. The hooks may be attached to the cable ends, for example by shrinkage or welding.
Kroge udformet pi denne måde har en flad profil som vist i 10 fig. 2. Dette muliggør, at tværstykkerne kan ligge tæt ved dækkets sidevægge, og at dækkæden kan anvendes på køretøjer, som har begrænset frigang imellem dækkene og karrosseriet. Da krogene ifølge opfindelsen kan være af forholdsvis lille størrelse i sammenligning med de øjekroge af cirkulær stangmateriale, som anvendes i mange 15 dækkæder, og da krogene ifølge opfindelsen er forbundet direkte med sidestykkerne, kan dækkædens vægt formindskes. Dette formindsker slitagen både på dækket og på kæden, således som det vil blive forklaret, og desuden formindskes kædens fremstillingsomkostninger.Hooks designed in this way have a flat profile as shown in FIG. 2. This allows the cross sections to be close to the sidewalls of the tire and the tire chain can be used on vehicles which have limited clearance between the tires and the bodywork. Since the hooks of the invention may be of relatively small size in comparison with the circular rod material eye hooks used in many tire chains, and since the hooks of the invention are connected directly to the side pieces, the weight of the tire chain may be reduced. This reduces wear on both the tire and the chain, as will be explained, and also reduces the chain's manufacturing costs.
Flere andre vigtige fordele samt forbedrede resultater opnås 20 med de ovenfor omtalte foretrukne udførelsesformer for opfindelsen.Several other important advantages as well as improved results are obtained with the preferred embodiments of the invention mentioned above.
For det første har det vist sig, at der opnås en betragtelig forøgelse i trækevnen ved at eliminere trækmufferne fra dækslidbanens midterparti og ved at begrænse mufferne til kun dækkanterne. Dette antages at skyldes, at størstedelen af dækkets trækkraft kommer 25 fra dets kanter, idet slidbanen i dækkets midterparti først og fremmest tjener som et forbindelsesmiddel imellem de to dækkanter. I et korrekt oppumpet og afbalanceret dæk er slidbanens centrum i realiteten en smule konkav, og området berører kun vejen. Følgelig er trækmuffer i denne del af dækket langt mindre effektive end trækmuf-50 fer på dækkanterne.First, it has been found that a considerable increase in traction is achieved by eliminating the tugs from the center portion of the tire tread and by limiting the tucks to only the tire edges. This is thought to be due to the fact that most of the tire traction comes from its edges, the tread of the tire's center portion serving primarily as a connector between the two tire edges. In a properly inflated and balanced tire, the center of the tread is in fact a bit concave, and the area only touches the road. Consequently, pull sleeves in this part of the tire are far less effective than pull sleeves on the tire edges.
For det andet formindskes slitagen på både dækket og dets dækkæde. Da trækmufferne er elimineret fra tværstykkernes midterdel, er slitagen på slidbanen formindsket. Endvidere formindskes tværstykkets masse i midterdelen ved at eliminere trækmufferne herfra.Second, the wear on both the tire and its tire chain is reduced. As the sleeves are eliminated from the center part of the cross pieces, the wear on the tread is reduced. Furthermore, the mass of the crosspiece in the center portion is reduced by eliminating the pull sleeves therefrom.
55 Når dækket roterer, løfter centrifugal kræfterne den midterste del af tværstykket længst muligt bort fra dækket, hvorved midterdelen accelereres til en højere hastighed og tvinges ned i vejen med den55 As the tire rotates, the centrifugal forces lift the middle portion of the crosspiece as far as possible away from the tire, accelerating the center portion to a higher velocity and forcing it into the road with it.

5 størst mulige slagvirkning. Ved at formindske tværstyk kernes masse i deres midterdele formindskes centrifugalkraften og dermed den slagkraft, som tværstykkerne udsættes for. Følgelig er slitagen pi tværstykkerne formindsket. Pi lignende måde og som tidligere beskrevet 05 formindsker krogene 26, der forbinder tværstykkerne 14 direkte med sidestykkerne, også dækkædens vægt. Dette bevirker en yderligere formindskelse af slitagen på dækket og pi kæden. Da dækkæden er lettere, er der mindre centrifugal kræfter, som trækker tværstykkerne ud af fra dækslidbanens midterparti. Krogene søger derfor at 10 glide højere op på dæksidevæggene og at holde trækmufferne i nærheden af dækkanterne og borte fra dækslidbanens midterparti.5 greatest impact. By decreasing the mass of the core pieces in their middle portions, the centrifugal force and thus the impact force to which the cross pieces are exposed is reduced. Consequently, the wear on the cross pieces is reduced. In a similar manner, and as previously described 05, the hooks 26 connecting the cross pieces 14 directly to the side pieces also reduce the weight of the tire chain. This further reduces the tire wear and tear on the chain. As the tire chain is lighter, there are less centrifugal forces that pull the cross pieces out from the center portion of the tire tread. The hooks therefore seek to slide 10 higher up on the tire sidewalls and to keep the pull sleeves near the tire edges and away from the tire tread center portion.
Desuden formindsker skruefjederen 46, der er fremstillet af elastisk materiale, slitagen på midterdelen 42 på tværstykkekablet 28, hvilket forlænger dækkædens levetid.In addition, the coil spring 46, made of elastic material, reduces the wear on the middle portion 42 of the cross-sectional cable 28, which extends the life of the tire chain.
